It will probably fit, but be of very poor quality. You probably want a 350mm wheel instead of a 320mm wheel. The 320mm wheel will block most of the gauge cluster... I also hope for your sake that the hub matches either the Momo or Sparco bolt pattern so you can get a nice wheel at some point instead of that piece of crap.
From the fact that you have trouble fitting in the car, I would imagine you don't have the height adjustable seat and tilt steering wheel?
For my car, I have a Momo hub adapter, Momo steering wheel and NRG quick release that moves the wheel about 1.5" closer to me. With the lower Celica GTS seats, it fits me perfectly (6'2" also). Of course, that's like $300+ of parts...
